Ever since its formation around 4.5 billion years ago (Neoproterozoic days), Earth’s rotation has been gradually slowing down. It’s a process that continues to this day, and estimates suggest that the length of a day currently increases by about 1.8 milliseconds every century. But why is the Earth’s spin slowing down?
The ozone layer acts as a shield for life on Earth, so when scientists discovered a hole in the ozone layer, it was a matter of grave concern. In this Breakdown, we discuss the steps taken to protect the ozone layer and why it’s important we continue to make strides.
Rain or shine, winter or summer, any time spent outdoors leaves your delicate skin vulnerable to sun damage. No matter where you are -- the beach, the mountains, or just walking down the street -- if you are outside, your skin is being pummeled by the sun’s invisible, damaging, and harmful rays.
Running around the backyard on warm summer nights in an attempt to catch lightning bugs is a fun pastime. These insects, also known as fireflies, can light up the night with their magical glow. But, what actually makes them flash? And why do they do it?
Have you ever woken up after a clear summer night to find the grass is wet, even though you know it didn’t rain overnight? The moisture on the grass is called dew. In this Breakdown, we discuss how dew forms.
The RMS Titanic is disappearing. The iconic ocean liner that was sunk by an iceberg is now slowly succumbing to metal-eating bacteria: holes pervade the wreckage, the crow's nest is already gone and the railing of the ship's iconic bow could collapse at any time.
The oceans cover about 70 percent of the Earth’s surface, and that about 97 percent of all water on and in the Earth is saline—there’s a lot of salty water on our planet. But, where did all this salt come from?
Those who live in hurricane prone areas understand how intense these storms can be, and these tropical systems have multiple threats. While many of us picture wind and storm surge at the coast, the risk from hurricanes extends inland.
When you think of lightning, you think of a thunderstorm. Many people also assume that hurricanes have a lot of lightning because they are made up of hundreds of thunderstorms. However, hurricanes do not typically produce lightning.
Without winds, the Earth would be inhabitable. Winds distribute heat energy over our planet. If we did not have any winds in the atmosphere, it would be extremely hot in the tropical regions and extremely cold in the northern regions.
